WebThe tan δ values for some commonly used organic solvents are summarized in Table 2. This table shows the classification of solvents into high (tan δ >0.5), medium (tan δ 0.1 to 0.5), and low microwave absorbing (tan δ <0.1). Solvents without a dipole moment, such as benzene and dioxane, are more or less microwave transparent (tan δ <0.01).
